Battleship
In 1850, the French Navy launched Napoléon, a 90-gun vessel that marked the first true steam-powered battleship. Henri Dupuy de Lôme designed this ship to carry conventional armament while using steam engines to achieve speeds independent of wind direction. This innovation gave naval commanders a potentially decisive advantage in engagement scenarios where weather conditions might otherwise dictate movement. By 1853, explosive shells had begun to render wooden-hulled ships vulnerable during conflicts like the Crimean War. The Battle of Sinop demonstrated how Russian ships could destroy Turkish frigates and corvettes with these new weapons. Yet wooden hulls remained surprisingly resilient against shell fire until ironclad technology emerged. In March 1858, France ordered Gloire, an ocean-going armored warship protected by thick iron plates over wooden hulls. Britain responded within months by launching Warrior, a larger ironclad with an all-iron hull completed in 1861. These vessels sparked immediate construction programs across Europe as navies realized traditional sailing ships were obsolete. During the American Civil War, the Battle of Hampton Roads in March 1862 settled debates about ironclad value when Virginia fought Merrimack to a standstill. From the 1860s through the 1880s, navies experimented with gun placement in turrets or barbettes while gradually removing masts from designs. Steel replaced iron and wood as primary construction material by the mid-1870s when French Navy laid down Gaulois. Gun manufacturers continuously increased caliber sizes to penetrate thicker armor, leading to ships carrying guns up to 14 inches in diameter. By 1893, Britain had built nine Royal Sovereign-class battleships armed with 12-inch guns that established patterns for future designs.
In early 1906, Britain launched HMS Dreadnought, a revolutionary ship that discarded medium-caliber secondary batteries entirely. Admiral Sir John Fisher designed this vessel to carry ten 12-inch guns arranged in twin turrets along the centerline. This configuration allowed all main armament to fire broadside simultaneously without interference from smaller weapons. Other major naval powers immediately began constructing their own dreadnoughts after seeing Dreadnought's capabilities. The Anglo-German naval arms race intensified dramatically following this launch. Germany responded with Nassau-class ships featuring hexagonal turret arrangements while Japan ordered Kongō-class battlecruisers. By 1910, British super-dreadnoughts carried even more powerful 15-inch guns on centerlines. Oil-fired propulsion systems became standard across new constructions, enabling faster speeds than coal-burning predecessors. The United States introduced all-or-nothing armor protection schemes starting with South Carolina-class ships laid down in 1912. These designs concentrated maximum armor thickness over machinery and magazines while stripping intermediate protection from non-essential areas. France adopted 34-centimeter guns for its Courbet-class battleships beginning in 1912. Japan followed suit with Fuso-class vessels armed with 14-inch main batteries. Naval theorists like Vittorio Cuniberti had published articles advocating such all-big-gun concepts as early as 1903. His ideas influenced Fisher's decision to build Dreadnought despite initial preferences for armored cruisers. Within seven years of Dreadnought's completion, every major naval power possessed either active dreadnought fleets or ships nearing completion. Even second-rank navies like Spain, Brazil, Chile, Argentina, Greece, and the Ottoman Empire began their own programs domestically or through foreign orders.
The Washington Naval Treaty signed in December 1922 imposed limits on battleship construction numbers and sizes among major powers. A ten-year building holiday prevented new launches except for two British Nelson-class ships permitted to match American and Japanese capabilities. These treaty battleships carried 14-inch guns while maintaining displacement ratios of five-to-five-to-three between United States, United Kingdom, and Japan. The First London Naval Treaty followed in 1930 setting additional restrictions before Japan withdrew from the system entirely in 1936. Most nations modernized existing fleets rather than building new vessels during this period. Britain refitted Queen Elizabeth-class ships through the 1920s adding anti-torpedo bulges and aircraft catapults. France built Dunkerque-class fast battleships armed with 33-centimeter guns starting in mid-1930s as response to German rearmament. Italy countered with Littorio-class vessels carrying 15-inch guns while Germany developed Bismarck-class ships after signing Anglo-German Naval Agreement in 1935. Nazi Germany's Plan Z program included eight planned battleships beginning with Bismarck and Tirpitz. Japan decided early in 1934 to build four Yamato-class ships armed with 46-centimeter guns though work started late 1937. All four classes received distinctive pagoda masts during upgrades alongside propulsion improvements increasing speeds significantly. French Richelieu-class ships prompted German construction of Scharnhorst-class vessels late in decade. British King George V-class ships laid down in 1937 carried 14-inch guns intended to comply with Second London Conference terms until Japan's refusal allowed United States to increase caliber to 16 inches for South Dakota-class designs.
On the 1st of September 1939, German pre-dreadnought Schleswig-Holstein fired the first shots of World War II bombarding Polish garrison at Westerplatte. Japanese surprise attack on Pearl Harbor on the 7th of December 1941 sank or destroyed five American battleships using dive-, level- and torpedo bombers. Three days later land-based aircraft sank British Prince of Wales and Repulse off British Malaya marking first time maneuvering capital ships were sunk by aircraft returning fire. During Guadalcanal campaign in November 1942, American battleships Washington and South Dakota intercepted and sank Japanese Kirishima despite receiving significant damage themselves. Battle of Leyte Gulf in October 1944 became one of history's largest naval engagements over several days involving multiple Japanese fleets attacking Allied invasion forces. Japanese battleship Musashi sunk by carrier aircraft during Sibuyan Sea fighting while Surigao Strait saw US battleships defeat Southern Force including two enemy vessels. Yamato launched final suicide mission against Okinawa beaches in April 1945 before being scored between nine and thirteen torpedo hits plus six bomb hits sinking her completely. Only Nagato survived the war ending with Japanese surrender aboard its deck in September 1945. European theater operations included Italian Taranto strike where Swordfish torpedo bombers disabled three battleships though all repaired subsequently. German Bismarck crippled by Swordfish torpedoes allowing British battleships to catch and destroy her during Denmark Strait action. Tirpitz destroyed by heavy bombers in Norway in 1944 after serving as fleet-in-being since 1942. By 1943 Italian operations sharply reduced due fuel shortages leading to country surrender and fleet internment at Malta.
After World War II most surviving pre-war American battleships were either scrapped or sunk as target ships by 1948. Four Iowa-class vessels remained until late 1950s and early 1960s when reactivated for Korean War gunfire support duties. USS New Jersey deployed during Vietnam War 1968, 1969 performing same coastal bombardment tasks. All four ships modernized early 1980s adding Tomahawk cruise missiles, Harpoon anti-ship missiles, Phalanx CIWS systems alongside latest radar equipment. Recommissioned under Ronald Reagan's 600-ship Navy program they saw renewed combat: New Jersey bombarded Syrian artillery during Lebanese Civil War 1982 while Missouri and Wisconsin participated Operation Desert Storm against Iraqi forces 1991. These expensive vessels required thousands of crew members proving unsustainable operationally so Iowa and New Jersey returned reserve by end decade. Missouri and Wisconsin decommissioned by December 1991 struck from Naval Vessel Register in 1995 marking no remaining active or reserve battleships worldwide. Eight US battleships now preserved as museums including Massachusetts, North Carolina, Alabama, Iowa, New Jersey, Missouri, Wisconsin, Texas. Missouri and New Jersey operate Pearl Harbor and Camden New Jersey respectively while Iowa displays Los Angeles Waterfront San Pedro California. Wisconsin serves Norfolk Virginia museum ship. Massachusetts never lost man service displayed Battleship Cove Fall River Massachusetts. Texas first converted to museum normally San Jacinto Battleground State Historic Site Houston closed repairs 2021. North Carolina Wilmington North Carolina Alabama Mobile Alabama. USS Arizona Memorial erected over wreck sunk Pearl Harbor attack 1941 commemorating killed raiders. Only other 20th-century battleship on display Japanese pre-dreadnought Mikasa preserved since 1923. On the 22nd of December 2025 United States Navy announced planned construction new battleships.
